ABSTRAK
Pencemaran air seperti logam berat dapat menurunkan kualitas dan kuantitas air. Enceng gondok {Eichhornia crassipes (Mart.) Solms} adalah salah satu cara untuk menjerap logam berat seperti Pb. Pada penelitian ini digunakan serbuk tangkai daun enceng gondok {Eichhornia crassipes (Mart.) Solms} kering mesh 30/40 untuk menjerap Pb. Kadar Pbdalam larutan dianalisis dengan menggunakan Inductively Coupled Plasma Spektrometer (ICPS). Hasil penelitian menunjukkan pada kadar awal Pb 2398,55 bpj diperoleh 103,30 mg Pbterjerap/g penjerap. Berdasarkan penelitian ini, dapat disimpulkan bahwa enceng gondok yang mana mudah didapat dan murah dapat dijadikan sebagai salah satu cara untuk menjerap Pb.

UPTAKE OF PbBY DRIED LEAF STALKS OF WATER HYACINTH {Eichhornia crassipes (Mart.) Solms} MESH 30/40
Abstract
Water pollution such as heavy metals can reduce the quality and the quantity of water. Water hyacinth {Eichhornia crassipes (Mart.) Solms} is one of the way to adsorb the heavy metals like Pb. On this research, the powdered of the stalk of dried water hyacinth {Eichhornia crassipes (Mart.) Solms} leaves (30/40 mesh) was used to adsorb Pb. Concentration of Pb in the solutions were analyzed using Inductively Coupled Plasma Spectrometer (ICPS). The result showed that on the initial Pb concentration, 2398.55 ppm was obtained 103.30 mg Pbadsorbed/g adsorbent. Based on this research, it is concluded that water hyacinth which is cheap and also easy to get can be one of the way to adsorb Pb.
